Describe the bug:
Once the user has selected a pre-defined date/time period, or once they have selected "Apply", the dropdown box is not dismissed. The user must clock outside of the drop-down box in order to have it dismissed.
Steps to reproduce:
1)Put a date/time filter element on a canvas in Kibana.
2)Put the canvas in full-screen mode.
3) Click on the filter element. The drop down box will appear that will allow you to select a date/time range (see attached screenshot).
4) Select any of the items on the right side of the drop-down (such as “Today”).

Expected behavior:
Once selected the drop-down box should automatically dismiss itself (close).

Observed behavior:
Instead, the user has to click outside of the dropdown in order to get the drop-down to dismiss).
